Pain Medicines: Different Types And Precautions

Pain medicines help people manage their ailments or symptoms from health conditions. They are often the first line of treatment because they are affordable, convenient, and effective. There are many kinds of medications, but the common ones are acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), and narcotics or opioids. Each type has its own set of benefits and downsides. Following the recommended dosage or prescription instructions is vital to avoid adverse risks or side effects.

Many people experience pain daily from an illness, muscle overuse, sudden injury, or chronic conditions. It may range from mild to severe, depending on the cause. This can limit normal functioning and interfere with regular activities. Likewise, it may worsen without diagnosis or treatment. Medicines provide individuals with a fast way to manage their symptoms. This guide will cover the different types of pain relievers, including their benefits, safety precautions, and best practices.

Different Types Of Pain Medicines

The first type of pain medicine is paracetamol or acetaminophen. It has an antipyretic agent that helps reduce fever. In addition, it works centrally in the brain towards the pain pathways, reducing pain perception. Paracetamols are available over-the-counter and are generally well-tolerated for mild to moderate pain, fever, headaches, and colds.

The second type is NSAIDs. They block the enzyme called cyclooxygenase (COX) used to produce prostaglandins. Prostaglandins are hormone-like substances made at the site of tissue damage. By reducing prostaglandin levels, they reduce swelling and inflammation. OTC NSAIDs are available, like ibuprofen, aspirin, and naproxen. However, if these do not work, a doctor may prescribe NSAIDs with higher doses.

Lastly, narcotics or opioids are strong forms of painkillers. They are available upon prescription due to their potent effects and risks of addiction. They work by binding to the pain receptors in the brain and spinal cord to reduce the symptoms. Opioid medications can be effective in managing long-term pain, such as cancer or following surgery or injury.

What They Can Treat

  • Paracetamol or acetaminophen: muscle pain or sorenessheadaches and migraines, fever, and burns. It also includes aches from colds, flu, bacterial infections, and other minor discomforts.
  • NSAIDs: inflammatory conditions, including arthritis painback pain, muscle and joint pain, headaches, muscle spasms, and menstrual cramps. It also helps relieve dental pain and post-surgical pain. NSAIDs can help nerve pains like sciatica, postherpetic neuralgia, and trigeminal neuralgia for temporary relief or short-term use only.
  • Opioids: persistent pain from cancer, surgeries, and trauma (broken bones, strains, and sprains). It also helps severe chronic conditions and nerve damage like fibromyalgia, multiple sclerosis, and other neuropathic pains.

Safety Considerations When Taking Pain Medicines

When taking pain medicines, it is essential to read the instructions and warnings to avoid potential risks and adverse effects. A standard guide would be to follow the frequency and dosage recommendation based on age. The labels indicate the amount required for an adult and children.

To avoid harm, know what is contained in each medicine, and do not mix two pain relievers without a doctor’s advice. Some have more than one active ingredient, so it is unnecessary to take another medicine. Doing so increases the risk of overdose. Additionally, some people have allergies to one of the ingredients. Thus, it may cause reactions and worsen the situation.

OTC medicines are suitable for short-term pain but may lose effectiveness with more severe medical conditions. Likewise, avoid taking OTC pain relievers continuously for several weeks to months. On the other hand, opioids are often given at the lowest dose possible for the shortest period of time. The risks also drastically increase if you use them in the long term without a guide. Therefore, always consult your healthcare provider for proper treatment when experiencing severe and recurring pain.

Common Side Effects Of Painkillers

OTC and prescription painkillers have common side effects, such as nausea, vomiting, dizziness, stomach upset, and diarrhoea or constipation. Many painkillers have a sedating effect on the body, which can make it difficult to stay focused and alert. Some medicines can also slow down the digestive system, leading to difficulty in passing stools.

Other side effects include dry mouth, high blood pressure, hypersensitivity reaction, heartburn, slowed breathing, itchiness, and ringing in the ears. NSAIDs can cause ulcers, increasing the risk of stroke or heart attack for people with a history of cardiovascular disease. Lastly, long-term intake may risk kidney and liver damage.

When To Take Pain Medicines

Many people take pain medicines as soon as they feel discomfort. However, there are certain guidelines to help take medications safely. It depends on several factors, such as the type and severity of the pain, the overall health condition, and the recommendations of a healthcare professional. OTC pain relievers can be taken as needed.

In cases of chronic or severe pain, individuals must follow the instructions of a doctor. Prescription NSAIDs and opioids should be taken as directed and not exceed the prescribed dosage. Excess amounts may lead to dependence or overdose. It is also crucial to note any side effects that may arise from these medications and inform your healthcare provider.

It is important to read the labels of each medicine and understand its intended use and dosage. Moreover, a pain specialist may also instruct the best time to take medications, such as before or after meals. Depending on the dose or type, drugs may require a frequency of once or twice a day or at regular intervals.

When To Seek For Professional Help

It is crucial to consult a health professional if you are experiencing persistent pain that lasts for more than a week. If the cause of the pain is unknown, it is advisable to get a diagnosis to identify the underlying issue. Hence, a doctor can prescribe a treatment, which may include medications and other methods like physical therapy and TENS (Transcutaneous Electrical Nerve Stimulation).

In addition, seek medical attention if you experience severe side effects or allergic reactions. Likewise, if there are accompanying symptoms like unexplained weight loss, difficulty urinating, and weakness in the legs may indicate a more serious condition.


Pain medicines can be an effective and convenient way to manage various chronic and acute pain. Different types vary according to how they interact with the body, what they treat, and potency. In particular, paracetamols help reduce fever and general body aches. Low doses are generally safe for adults and children. On the other hand, NSAIDs help lessen inflammation. Lastly, opioids or narcotics are stronger painkillers that are suitable for severe or chronic pain.

Although they are effective, it is important to take them as directed. Medications can include side effects, such as drowsiness, stomach pains, and constipation. In addition, long-term intake of over-the-counter drugs may also cause organ damage. If side effects persist or the pain worsens, seek medical attention to address the issue. Overall, follow the recommended guidelines to prevent adverse health risks. You may also consider complementary techniques to maximise pain relief.
